T 0 all whom it may concern Be it lmown that I, MARVIN H. J ESTER, a citizen of the United States of America, re siding at the city and county of Denver and State of Colorado, have invented a new and useful Clamping-Clip Mechanism for Securing Plaster-Boards to Metal Studding, of which the following is a specification.

My invention relates to a new clamping clip mechanism for securing plaster boards to metal studding, the said plaster board metal stud partition being used in the form of a core that is adapted to receive and support plastering materials used in the construction of plastered partition walls in buildings; and the Objects of my invention are:

First, to provide a fire-proof plaster board supporting and clamping device for the construction of partition walls for receiving plastering mortars and cements in the construction of plastered walls in buildings.

Second to provide a plaster board clamping and supporting device that can be used to support and secure plaster boards in partition form, and to secure them to the walls of buildings. And

Third, to provide a corner clamping device for turning angled corners in partitions constructed of my plaster board supporting and clamping device.

I attain these objects by the mechanism illustrated in the, accompanying drawings, in which:

Figure 1, is a perspective view showing a portion of a channel bar stud and plaster boards secured thereto, by the improved supporting and clamping clips.

Fig. 2, is an end view of the construction shown in Fig. 1.

Referring to the drawings,-

The numeral 1 designates a channel iron stud of iron or steel. 1 preferably use one inch channel studs, as this size of channel makes a plastered partition that is one and threequarters to two inches thick, and this thickness makes a partition that is stronger and cheaper and more sound-proof as well as vermin proof, than wooden partitions from four to six inches in thickness. Channel bars of smaller or larger sizes may be used, however, if it is desired to make partitions of less or greater thickness than two inches. These channel bar studs take the place of wooden studs in wooden partition construction, and are positioned at such distances apart vertically between the floor and ceiling beams of buildings as will support between them the size of plaster boards that are used in this class of fireproof plastered partitions. The plaster boards that are used in this class of partition construction are made in sizes of various lengths and widths, the most general sizes made being 24, 30 and 36 inches long, and from 18 to 36 inches wide, and varying from one-quarter inch to three-quarters of an inch in thickness. The channel bar studs are consequently set generally 18 or 24 or 30 or 36 inches apart, but can be set any distance apart to receive between them and their supporting clips plasfor boards that are made of any desired width.

The metallic studs used may be a fiat bar of iron or steel as shown in my Patent Number 1,001,146, issued to me August 22, 1911,

support plaster boards of any thickness and of any length. The channel studs 1 extend from the floor oists E2, to the ceiling oist 3, and are secured thereto in any suitable manner. I preferably, however, bolt them at their opposite end to a bar 4 of angle iron, by bolts 5. The bar t is secured by nails or screws that extend through holes in the an gle bars to the floor and ceiling joist (see Fig. 6). The channel bars are set edgewisc across the length of the partition, and upon them are mounted at preferably eight inches apart, the supporting clips 6, and between each two adjacent clips I place a clamping the center of each to the center of the supporting clips on each side of each clamping clip. The supporting clips are U-shaped clips, and the free end portions of each clip are each provided with a laterally extending wing portion 8. These clips are formed of blank strips of iron or steel that are of a length to form the entire clip, and these strips are bent into their U-shape form and the closed end portion of the yokeof the clip is formed to fit snugly over one edge of the channel bar, and against its edge, while the open or free ends of the yoke portion of the clip are arranged at such a distance apart relative to the thickness of the edges of the channel bar as will cause them to be sprung over the edges of the channel bar and with sufficient resilient pressure to hold the clip by its elastic pressure at any point along the length of the channel bar without slipping or falling from where it is placed by the operator.

The wings 8 are arranged and made deep enough to extend from one edge of the channel bar over its opposite sides, and may extend part way to or even with or a short distance beyond the opposite edge of the channel iron, as illustrated. The outer surface of its wings, at the outer edges of the free ends of its yoke portion, extend beyond the. opposite edge of the channel bar about an eighth of'an inch, which is the preferred arrangement of my improved plaster board and metallic partition stud clamping device. Thewings 8 are made long enough'to re- The clip is pressed by the operator against the plaster boards and is arranged to be pushed into engagement with and to lock with a frictional locking pressure against the adjacent edge of the channel bar stud. This 7 clamping clip forms the essential element of;

my present invention, and it comprises a channel shaped piece of sheet steel, iron or other suitable metal, that is made long enough to extend over and beyond the opposite sides of the channel bar stud a suflicient distance to form a bearing of sufficient length against the plaster boards to clamp them firmly against the plaster board. The sides 11 and 12 of this channel shaped clip are provided with two slots 13 and 1%,which V V extend from their edges to within about an eighth of an inch of the plate vofthe channel bar. These slots are arranged to leave narrow side portions 16 between the top of the 1 slots and the plate portion of the clip,which form truss members that stiffen the clip at These slots 18 its center above these slots; and 14 are made wide enough to permit the clip to be placed over the edge of the chain nel bar stud loosely, and to bear against the plaster boards, and with the edges of its i I sides, while its plate portion stands about an 7 form two slightly tapering lipsZO, which are arranged to engage the under side 22 of the adjacent angled edge 2370f the channel bar stud, and wedge or force the clips side edges down against the plaster boards The ends 24 of the sides along the recesses, extend into the channel space under the edge 7 23 of the channel bar stud. The edges of the sides of these clamping clips are so arranged relative to the slots 18 and the edge 23 of the channel bar'and the surface of the plaster boards, that when the operator wishes to apply the clamping clip he presses down on it hard enough to bend or spring the part of the plaster boards down enough to allow the side lips 20 to be pushed under the edge 23 of the channel bar stud, and then when the ressure against the plaster board 1 20 of the clips to bear with a clamping re 5 wings of the supportlng clips a clamping V silient pressure against the under sideof the edge '23 of the channel =bar, thus --clamping the plaster boards to the supporting clips and to the channel bar stud.

These channel forms of clamping clips are provided with apertures 25 through their plate portions, which are made large enough to allow plastering mortarlto flow easily through them into their channel space partition to nail :picturemoldstrips to; and

also close enough to the fioor portion of the partition to nail base-boards andtheirmolding member to. The grounds 21 have their the partition.

I have illustrated grounds in Fig. 6, positioned to receive picture molding =or nails for hanging pictures, and also for securing base boards 1 and their moldings to, and they can be inserted wherever desired-along the height of the partition. I

l/Vhile l haveshownthis channel form of clip made-of plain smooth iron, itcanalso i f desiredbem'adeo-f corrugated-iron or be pro =vided with ribbed portions'to strengthen it.

'In Figs. 7 and 8, I illnstrateaslight modification of the clamping clip. In this modification'the arrangement of the channel bar stud and the supporting clip is the same. The damping clip itself, :however, is formed of a ribbon strip of flat-iron bent so as to form 'two flat oppositely extending wings 26 and 27 and upright angledsides 28 and 29 between the Wings, the sides 28 and 29 being separated far enough apart to form a space 30 between them wide enough to allow them to pass loosely over the edge of the channel bar stud, and is also bent to 'form an overhanging lip portion 3'1 ha'vling a space 32 between the folds :in the metal that form the lip that is arranged to allow this hollow =lip to be pushed over the :side edge of the channel bar stud, and consequently allows'thishollow lip to incase the side and top and the *under p'a-rt 'of the adjacent edge o'ffthe channel stud. The lower edgeofthe foldinthe strip that forms the overhanging lip is arranged with a downward angled or wvedge shaped surface which with its overhanging lip is arranged to *be pushed'underthe adjacent edge of thechannel stud and bears against it and forces the wings of this clip to clamp themselves against the adjacent surfaces ofthe'plaster boards onopposite sides of the channel stud.

This ribbon shaped clip is consequently placed over the "edge I of the channel stud and is pushed under its edge and clamps against the under side of this edge and against the ends of the plaster boards on opposite sides'of the channel-stud,'the same as the channel form of stud shown in Figs. 1,2, 3, and t.

In F-igs. 9, 10, 1 1, and 12, 1 illustrate an adaptation of the clamping and supporting clip to the terminal ends of partitions to secure themto wooden grounds built into I employ a supporting clip 33, having the U shaped stud engagingportion 34:, and one plaster board supporting wing 35, the other wing being dispensed with. The supporting clip is sprung upon the stud, which abuts against the outside face of a door frame or other wooden member 36, as shown, to which the adjacentend of the partition is to be secured, and in order to fasten :the stud securely to the said door frame, I employ a combined stud supporting-and plaster board-clamping clip 37 which isconstructed as follows:

The clip 37 is similar in cross-section to the clamping clip shown in the foregoing views, but it is provided on one end with recesses 38, which receive one of the wings of the channel stud, this end of the clip being flush with the bottom member of the channelstud, when secured thereon, as will be understood by reference to Figs. 9 and 10,

the walls ofbuildings. In this adaptation,

so as to abutagainst thesaid door frame.

Theoppositeend ofthe bottom of the clip is formed with parallel slits which extend inward a suitabledistance, and thatgportion 'of the bottom released thereby is bent inward at rightangles,'orso as to lie between-the sides of the clip, to form r a nail supporting plate 39, the plate being provided with -a nail receiving aperture 40. Whenthe clip is placed upon the channel s'tud,-a space is left between thebottomof the'clip and -the adjacent side'of the-stud, sufficient to permit a nail 41, which is inserted in the aperture 40, to pass between the bottom of the clip and the side of the channel stud, and be driven into the-said door frame, as will be fully understood by reference to Fig. '10. By thismethod, the clip 37 not only serves to clamp'the plaster boardagainst the wing 35 of the supporting clip 33, in'like manner as the; clip shown in Fig. 1, butitalsoserves to rigidly secure the channel stud to the buck 36, so that the end of the partition abuttingagainst the said buck willalso be rigidly supported.

In Fig. 12, is illustrated a modification-of the clip 37 comprising a clip 42,- in which the nail supporting plate 39 is dispensed with, and theopposite end 43 of the bottom of'the clip is extended beyond the sides-thereof, and is 'V-shaped, as:shown, the pointed end thus formed being driven into the door :frame, and thusitaking ithe place of the =nail 41. The adjacent ends of the side'members of this clip are provided with recesses 44:, for the reception of one of the side members of the channel stud, the clip being adapted to engage the channel stud, and clamp the plaster boards thereto, the same as in the case of the clip 37.

Fig. 13 illustrates a corner clip 45 and the manner in which it is used to secure the adjoining ends of plaster boards in forming corners. In this connection an angle bar form of stud 46 is employed, and the clip is placed against the open side of the stud and bent around the same so as to lie against the sides thereof, the wings being then bent at right angles to the respective portions lying against the stud, and in line with the apex of the stud, as shown by 47, after which the remaining portions of the said wings are bent back parallel with the respective sides of the stud, as shown by 48, a space being left between the portions 48 and the portions which engage the stud suificient to receive and hold the plaster boards without the employment of any additional means.

In operation, the studs are secured to the floor and ceiling, at predetermined intervals, and the supporting clips are sprung upon the studs, at suitable intervals, corresponding to the widths of the plaster boards, or the said clips may be secured to the studs as the work progresses, in position to' form supports for the plaster boards which are laid against them, one above the other, from floor to ceiling. After the boards are placed, the clamping clips are placed over the studs and against the adjoining ends of a pair of boards, and then pressed to one side so that the edges of the recesses in their side members frictionally engage the adjacent side of the channel stud, whereby they are clamped to the said stud and against the adjoining ends of the plaster boards, which are thus clamped between the said clamping clip and the wings of the supporting clips. The supporting and clamping clips may alternate at regular intervals, or a clamping clip may be placed adjacent to a supporting clip, as shown by Fig. 6, or each clamping clip may be placed directly over a supporting clip, as shown in Fig. 4. Vhen the plaster boards have all been secured, the usual rough and finishing coats of plaster are applied, thus completing the partition.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is: V
